Nickel tetrafluorideNickel tetrafluoride is an inorganic compound with a chemical formula.SynthesisNickel tetrafluoride is claimed to result from the reaction of hexafluoronickelate) with [Arsenic pentafluoride|] and [Potassium hexafluoronickelate(IV)|] with [Boron trifluoride|].Chemical propertiesNickel tetrafluoride is an extremely strong oxidizer. The oxidizing properties are enhanced in presence of Lewis acids in anhydrous HF. In terms of oxidizing power, it is comparable to krypton difluoride. It can oxidize bromine pentafluoride to hexafluorobromonium cation, potassium hexafluoroplatinate to platinum(VI) fluoride.
